.Sh NAME
.Nm zfs-mount
.Nd manage mount state of ZFS filesystems
.Sh SYNOPSIS
.Nm zfs
.Cm mount
.Nm zfs
.Cm mount
.Op Fl Oflv
.Op Fl o Ar options
.Fl a Ns | Ns Ar filesystem
.Nm zfs
.Cm unmount
.Op Fl fu
.Fl a Ns | Ns Ar filesystem Ns | Ns Ar mountpoint
.
.Sh DESCRIPTION
.Bl -tag -width ""
.It Xo
.Nm zfs
.Cm mount
.Xc
Displays all ZFS file systems currently mounted.
.It Xo
.Nm zfs
.Cm mount
.Op Fl Oflv
.Op Fl o Ar options
.Fl a Ns | Ns Ar filesystem
.Xc
Mount ZFS filesystem on a path described by its
.Sy mountpoint
property, if the path exists and is empty.
If
.Sy mountpoint
is set to
.Em legacy ,
the filesystem should be instead mounted using
.Xr mount 8 .
.Bl -tag -width "-O"
.It Fl O
Perform an overlay mount.
Allows mounting in non-empty
.Sy mountpoint .
See
.Xr mount 8
for more information.
.It Fl a
Mount all available ZFS file systems.
Invoked automatically as part of the boot process if configured.
.It Ar filesystem
Mount the specified filesystem.
.It Fl o Ar options
An optional, comma-separated list of mount options to use temporarily for the
duration of the mount.
See the
.Em Temporary Mount Point Properties
section of
.Xr zfsprops 7
for details.
.It Fl l
Load keys for encrypted filesystems as they are being mounted.
This is equivalent to executing
.Nm zfs Cm load-key
on each encryption root before mounting it.
Note that if a filesystem has
.Sy keylocation Ns = Ns Sy prompt ,
this will cause the terminal to interactively block after asking for the key.
.It Fl v
Report mount progress.
.It Fl f
Attempt to force mounting of all filesystems, even those that couldn't normally
be mounted (e.g. redacted datasets).
.El
.It Xo
.Nm zfs
.Cm unmount
.Op Fl fu
.Fl a Ns | Ns Ar filesystem Ns | Ns Ar mountpoint
.Xc
Unmounts currently mounted ZFS file systems.
.Bl -tag -width "-a"
.It Fl a
Unmount all available ZFS file systems.
Invoked automatically as part of the shutdown process.
.It Fl f
Forcefully unmount the file system, even if it is currently in use.
This option is not supported on Linux.
.It Fl u
Unload keys for any encryption roots unmounted by this command.
.It Ar filesystem Ns | Ns Ar mountpoint

The command can also be given a path to a ZFS file system mount point on the
system.
